GUS-QS0B-03-4870-JF Description

The GUS-QS0B-03-4870-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 487Ω resistance value and a tight ±5% tolerance. The network operates within a wide temperature range of 70°C to 125°C (derated) and can withstand a maximum operating temperature of 125°C, making it suitable for demanding environments. With a ±25ppm/°C temperature coefficient, it ensures stable performance under thermal variations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating enhance its reliability in circuit designs requiring consistent power dissipation.
